Description

Technical Field

[0001] This invention relates to the field of microwave technology, and in particular to a method, apparatus, equipment, and storage medium for microwave reactor mesh generation and modeling. Background Technology

[0002] Microwave technology is currently widely used in chemical, biological, and electronic communication fields. Microwave heating is a common heating method for the rapid pyrolysis of biomass. Compared with other pyrolysis methods, it has the characteristics of fast heating rate, short residence time, and moderate pyrolysis temperature, and therefore has promising research and development prospects in the field of chemical applications.

[0003] Currently, in rapid heating applications involving large-scale microwave equipment with high field strength and high power, microwave reactors are typically designed based on multimode resonant cavities with multiple microwave sources coupled together, due to limitations in the scale and cost of a single microwave source. Therefore, when standing waves, reflected waves, and other interference phenomena exist between the microwaves from multiple sources, causing a decrease in microwave heating efficiency, or when process conditions such as operating conditions, reactants, and product requirements change, adjustments need to be made to the design schemes such as the cavity structure and the arrangement of microwave sources within the cavity.

[0004] There are many existing methods for technically adjusting microwave reactors. The mainstream approach is to use electromagnetic simulation software to simulate the field strength inside the cavity, and then make appropriate adjustments based on the simulation results.

[0005] The inventors discovered through research that the existing methods of simulating field strength using electromagnetic simulation software have at least the following drawbacks:

[0006] Mesh creation is a crucial step in microwave reactor modeling, directly affecting the convergence and accuracy of the simulation calculation of the electromagnetic distribution inside the cavity. In particular, mesh generation methods based on hexahedral meshes are difficult to generate automatically by the software itself, requiring multiple manual adjustments to the mesh generation, which in turn affects the generation efficiency and usability of the microwave reactor simulation model.

[0048] Beneficial effects

[0049] In this invention, a material medium database, a microwave reactor database, and a case study database are first preset. Then, when performing three-dimensional electromagnetic field simulation based on a scaled reactor model of a physical microwave reactor, the current physical quantities are acquired in real time. Then, the corresponding current reactant is determined based on the current physical quantities, which is equivalent to knowing the change information of the reactant in real time. Next, the appropriate mesh division strategy in the scaled reactor model is determined based on the current reactant. In this way, through this invention, the corresponding mesh division optimization scheme can be set according to the continuous changes in the material properties in the process flow.

[0050] Because the grid in the proportional reactor model of this invention can be automatically and dynamically divided to adapt to changes in the reactants, the efficiency and effectiveness of the control strategy for generating a solid microwave reactor are enhanced when performing three-dimensional electromagnetic field simulation.

[0051] This invention significantly shortens the initial modeling and design time for microwave reactors. By adapting the reactor to the specific process, it simplifies the selection of reactors for target processes, making convergence easier. Furthermore, existing techniques rely on empirically generated meshes based on actual reactor geometry, which may not be suitable for the actual computational process. Therefore, this invention dynamically divides the mesh according to needs and the intensity of material reactions within the reactor, further improving heating efficiency. Simultaneously, this invention replaces manual mesh division with artificial intelligence algorithms. By leveraging machine learning to predict existing operating conditions and combining a database of case studies, it overcomes the limitations of traditional optimization processes that require a predetermined reaction model before optimization, thereby enhancing the control of various physical quantities within the microwave reactor. Through dynamic mesh partitioning, the distribution of key physical quantities changes in real-time within a step size according to subjective and objective conditions, transforming the control problem into a regional partitioning problem within the cavity. This greatly improves the overall controllability and randomness of the microwave reactor, expanding both the optimization of modeling methods and the adaptability and practicality of microwave reactors in chemical processes.

[0059] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] Example 1

[0061] To improve the generation efficiency and usability of microwave reactor simulation models, refer to Figure 1 This invention provides a method for mesh generation and modeling of microwave reactors, including:

[0062] S11. Preset material medium database, microwave reactor database, and calculation example database;

[0063] The material medium database includes physical property parameters of various reactants; these physical property parameters include type, density, water content, complex permittivity, isobaric heat capacity, and thermal conductivity.

[0064] The microwave reactor database includes multiple microwave reactors with different operating parameters. The operating parameters include the shape, size, materials used, process design conditions, microwave source arrangement, number of microwave sources, and microwave source power of the inner and outer cavities of the microwave reactor, which can characterize the thermal efficiency of the microwave reactor.

[0065] The example database includes actual calculation results of the known physical property parameters in a microwave reactor with known operating conditions; the actual calculation results include calculation results for each time step period generated by three-dimensional electromagnetic field simulation calculation with a preset time step as the calculation period and the physical property parameters and the operating conditions as input parameters; the calculation results include one or more of temperature, pressure drop, pressure difference and composite results.

[0066] In practical applications, the actual calculation results corresponding to the example database can provide a reference for the artificial intelligence algorithm in the embodiments of the present invention, such as as the basis of training data, or as a reference for one or more of the following: initial training values, boundary conditions, steady-state reactor relative error, and transient reactor relative error.

[0067] S12. Generate a scaled reactor model of the physical microwave reactor through physical modeling; and determine the compatible microwave reactor that is most similar to the physical microwave reactor from the microwave reactor database.

[0068] In practical applications, when performing a proportional physical model of a solid microwave reactor, if the shape, size, materials used, process design conditions, microwave source arrangement, number of microwave sources, and power of the internal and external cavities of the solid microwave reactor have been determined, a proportional reactor model of the solid microwave reactor can be generated based on the existing operating parameters of the solid microwave reactor.

[0069] If the selection of the physical microwave reactor is still unclear when performing a scaled-down physical model of the reactor, the material medium database and algorithm database can be called up to convert the internally stored data into digital signals and inject them into the detector. The detector then uses artificial intelligence algorithms to complete the microwave reactor selection, thereby determining the operating parameters of the physical microwave reactor that are compatible with the physical properties of the reactants in the actual production process. Based on these operating parameters, a scaled-down reactor model of the physical microwave reactor can be generated.

[0070] Specifically, methods for generating a scaled-down model of a physical microwave reactor can include:

[0071] A scaled reactor model of the solid microwave reactor can be generated based on the existing operating parameters of the solid microwave reactor, or a microwave reactor with suitable operating parameters can be determined from the microwave reactor database based on the physical property parameters of the reactants.

[0072] After generating a scaled-down reactor model based on the actual microwave reactor, the most closely matching microwave reactor can be determined from the microwave reactor database.

[0073] S13. The internal logic of the proportional reactor model is divided into multiple segments; each segment is pre-divided into multiple grids;

[0074] The internal logic of the proportional reactor model is divided into multiple sections, and each section is regarded as an independent reactor individual connected in series.

[0075] In this embodiment of the invention, the number of sections logically divided into the internal cavity of the proportional reactor model can be determined according to actual process requirements. For example, for pyrolysis reactions, it is necessary to include a preheating section, a heating section, and a constant temperature section; for processes such as microwave drying that require a specific outlet temperature, a cooling section may also be provided after the constant temperature section.

[0076] In practical applications, the mesh divided in the embodiments of the present invention can be a hexahedral mesh or a tetrahedral mesh.

[0077] S14. Perform three-dimensional electromagnetic field simulation based on the scaled reactor model, and obtain the current physical quantities of each grid in the scaled reactor model in real time; the physical quantities include one or more of temperature, humidity, electric field strength, pressure and velocity field.

[0078] This step involves performing a three-dimensional electromagnetic field simulation using a scaled reactor model. By acquiring the current physical quantities of each grid within the scaled reactor model in real time, it is possible to continuously monitor whether the reactants within each grid are changing.

[0079] S15. Determine the corresponding current reaction material from the material medium database based on the current physical quantity, and determine the corresponding actual calculation result from the calculation database for the adapted microwave reactor;

[0080] When changes in the current reactants are detected based on the changes in the current physical quantities of each grid within the proportional reactor model, the appropriate reactants can be determined from the material medium database, and the appropriate microwave reactor can be determined from the reactor database. Specifically, this can include:

[0081] The corresponding current reaction material is determined from the material medium database based on the current physical quantity; then, the corresponding actual calculation result is determined from the calculation case database based on the adapted microwave reactor and the determined current reaction material.

[0082] S16. Based on the current reactants and the proportional reactor model, and taking the actual calculation results as the optimization target, generate a grid partitioning optimization strategy for each segment in each time step period using an artificial intelligence algorithm.

[0083] The actual calculation results include the calculation results for each time step period generated by the three-dimensional electromagnetic field simulation of the microwave reactor in the example database. This allows for the identification of the appropriate microwave reactor and the corresponding actual calculation results for the current reactants.

[0084] Using actual computational results as a reference for optimization targets can accelerate the convergence speed and effectiveness of generating mesh partitioning optimization strategies for each segment within each time step period using artificial intelligence algorithms. This involves determining different mesh partitioning accuracies for each segment and then partitioning the mesh according to different accuracies for each segment. Each partitioned mesh cell stores different physical quantities based on data type differences, including but not limited to one or more of temperature, humidity, electric field strength, pressure, and velocity fields.

[0085] S17. Update the mesh division of the preset section in the proportional reactor model according to the mesh division optimization strategy and return to step S14.

[0086] By continuously refining the mesh of sections in the proportional reactor model using newly generated meshes and optimization strategies, dynamic mesh updates can be achieved.

[0087] In this embodiment of the invention, either all segments can be dynamically updated, or one or more segments that have a significant impact on the reaction process can be selected as preset segments for dynamic updating, thereby reducing the overall computational load and improving computational efficiency.

[0088] In summary, the embodiments of this invention can significantly shorten the initial modeling and design time for microwave reactors. By adapting the reactor, the selection of the reactor corresponding to the target process can more easily achieve convergence. Meanwhile, existing technologies rely on experience to generate meshes based on the actual reactor geometry, which may not be suitable for the actual computational process. Therefore, the embodiments of this invention can dynamically divide the mesh according to needs and the intensity of the material reaction within the reactor, further improving the heating effect. Furthermore, the embodiments of this invention use artificial intelligence algorithms to replace manual mesh division. By leveraging machine learning to predict existing operating conditions and combining a database of computational examples, it overcomes the limitations of traditional optimization processes that require a predetermined reaction model before optimization, thereby strengthening the control of various physical quantities within the microwave reactor. Through dynamic partitioning of the mesh, the distribution of corresponding regions for key physical quantities can change in real time within a step size according to subjective and objective conditions, transforming the control problem into a regional partitioning problem within the cavity. This greatly improves the overall controllability and randomness of the microwave reactor, expanding both the optimization of modeling methods and the adaptability and practicality of microwave reactors in chemical processes.

[0089] Example 2

[0090] Based on the technical solution described in Embodiment 1, such as Figure 2 As shown, the embodiments of the present invention may further include the following steps:

[0091] S18. Perform three-dimensional electromagnetic field simulation based on the scaled reactor model updated by the mesh partitioning optimization strategy and generate the current control strategy for the solid microwave reactor.

[0092] The process of performing three-dimensional electromagnetic field simulation on the scaled reactor model is synchronized with the actual production process of the physical microwave reactor. Therefore, the current control strategy of the physical microwave reactor can be generated based on the real-time generated mesh partitioning optimization strategy. The current control strategy can then be converted into a control signal, and the microwave source in the physical microwave reactor can be controlled using a PID control algorithm to achieve the above control strategy.
